--- Comment #18 from Roderick Colenbrander thunderbird2k@gmx.net 2008-05-30 15:58:12 --- The program does a lot of wgl pixel format related queries. Perhaps some of the info confuses it. Further I'd like to see what pixel format it wants to set on the hdc (0x14f4). To figure that out I would add a line like this to the either internal_SetPixelFormat or just X11DRV_SetPixelFormat inside dlls/winex11.drv/opengl.c. Add this: TRACE("physdev=%p, HDC=%#x, iPixelFormat=%d\n", physDev, physDev->hdc, iPixelFormat);
In the end a log of +x11drv,+wgl could be useful too.
